NooElec R820T
Extend Your Antenna
The antenna supplied with the NooElec R820T devices is pretty short. You can run
a longer antenna over a window ledge, or to craft a more optimal antenna, see the
tutorial at
http://www.balarad.net
.
For most purposes, however, the NooElec's in-
cluded antenna will suffice.
Set Up the Code
To get started, update Raspbian and install the dependencies needed for building
Dump1090:
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install git-core git make cmake libusb-1.0-0-dev build-
essential pkg-config
Once finished, check out a copy of the source code of the drivers for the RTL-SDR
device, and then build and install them on your Raspberry Pi:
cd /opt/
git clone git://git.osmocom.org/rtl-sdr.git
cd rtl-sdr
sudo mkdir build
cd build
sudo cmake ../ -DINSTALL_UDEV_RULES=ON
